.ocdata missing - am I missing a vm hard disk?

Hi and hopefully someone can help me out.
Running Hansson made VM with 2 additionial virtual hard disks.
df -h and my largest hard disk doesn’t show up. (100gb ).
http://Nextcloud.lan displays login page - https://nextcloud.lan doesn’t. It says;
“Your data directory is invalid. ocdata in root etc…”

Can’t locate/find .ocdata in root, if root is /var/www/nextcloud/ .

Hopefully someone can guide me in the right direction here… thanks!

Info from vmware workstation:
hard disk scsi: 0:0 40 gb
hard disk 2 scsi: 0:1 40 gb
hard disk 3 scsi: 0:2 210 gb

disk number 3 is missing in nextcloud

I believe it’s /dev/sdc1 that is missing. I have no clue how to get it back…
